want to preserve my ntfs permission..

hi guys.. we are moving our data from servers (win2k servers) to SAN and i know that if i move my data on different disk then i will loose all of the permission/security/shared drives,folders. i dont want to loose all these things as there are hundreds of users and shared folders and you can imagine how tough it is to implement all of the settings again.i have found one command in resource kit to get a list of users permission on one particular drive or folder (which is slow by nature) so i cant use it for all of the drives/folders. so guys do you know any program or utilities which can prevent me fallin into the trouble.. i will appreciate your response…thanx, kutub bhungrawala
